gae撈出的query要怎麼比較?

[amorr (喵喵)]

　我有一個GAE 資料庫的class包含:
    author = db.StringProperty()
    content = db.StringProperty(multiline=True)
    lonx = db.FloatProperty()
    lony = db.FloatProperty()

  因為GAE好像不行過濾兩個變數:

  query = db.GqlQuery("SELECT * FROM Greeting where lonx >= :1 and lonx <= :2
  and lony>=:3 and lony<=:4"
, (float(self.request.get('x')) - 0.0001), (float(self.request.get('x')) +
0.0001),(float(self.request.get('y')) - 0.0001), (float(self.request.get('y')) +
0.0001) )

  所以我把它寫成
  query1 = db.GqlQuery("SELECT * FROM Greeting where lonx >= :1 and lonx <= :2"
, (float(self.request.get('x')) - 0.0001), (float(self.request.get('x')) +
0.0001) )

  query2 = db.GqlQuery("SELECT * FROM Greeting where lony >= :1 and lony <= :2"
, (float(self.request.get('y')) - 0.0001), (float(self.request.get('y')) +
0.0001) )

  可是卻不知道怎麼取query1和query2交集
  不知道板上的各位大大有沒有什麼辦法?
  謝謝!!

推 derekQQ:query1和query2都改成query就行了，query是累加的
→ derekQQ:sorry，好像錯了，query1結束可以改用query.filter
推 derekQQ:query1 = db.GqlQuery....
→ derekQQ:query1 = query1.filter(...
